Products purchased on the Hydro Flask website can be returned to Hydro Flask for a full refund within 30 days of the purchase date. In order to be eligible for a return, products must be in an unused condition with their original packaging intact.

My Hydro Orders: Because all My Hydro™ orders are made to be uniquely you, they are not eligible for returns.
